I have 4 blown speakers too
But I set them to only to high pitch
So basically only using them as tweeters
And all my bass from the sub,
Works but no, mid-range tones

Speakers
 

I Just Ran With Kenwood Rear Speakers And Infinity Fronts All Stock Size. 2 12 Inch Subs And A 600 Watt Boss War Series Amp. If Your Looking For Cheapo Stuff Goto Teptronics.com Pretty Good Site. I Had 2 6.5 Legacy Speakers In My Dodge Omni In The Front And They Sounded Like They Were Twice That Size. Would Have Been Nice To Know 5.25 Fits Tho. I Would Have Dropped 4 5.25s With Bass Blockers On Them And Let The Subs Carry The Bass

So you all know, all speakers (pioneer, infinity, sony, JBL, ect, ect..) are made by Vifa. Look for Vifa on partdirect.com your only paying for the name of whatever speaker you buy, the only thing that matters is buying the right speaker IE. the material it's made from. Because there is only 3, well now 2 speaker companies in the world, everything else is just bought wholesale mainly from Vifa.:squint:
